In recent years the global shipping industry has taken significant steps toward reducing sulfur emissions on merchant ships. In 2015, SECA trade partners restricted sulfur emissions to 0.1% sulfur content within 24 nautical miles (or less) from shore. And on January 1, 2020, the International Maritime Organization’s (IMO) revised MARPOL Annex VI rule will come into effect, which will lower the maximum global sulfur cap for emissions from 3.50% to 0.50%. To ensure compliance with both regulations, merchant ships will need to strictly monitor sulfur content in fuel.
For vessel owners and ship operators, it is of critical importance to optimize engine performance to reduce costly repairs and ongoing costs. This will only escalate with the new sulfur regulations leading to an unavoidable increase in fuel costs due to the high cost of the desulfurization process. With a glut of vessels in operation and pressure to reduce speed to improve fuel efficiency, vessels are slow steaming (reducing speed to between 18-26 knots). If not managed properly, slow steaming can result in cold corrosion which can lead to engine liner failure and detrimental engine damage. To properly mitigate fouling and cold corrosion, adjustments to feed rates and the Base Number (BN) of the oil used are essential. To make these decisions, engineers need accurate and timely measurement of iron (Fe), calcium (Ca) and sulfur (S).
Petra MAX delivers rapid and precise sulfur testing with a limit of detection as low as 0.0006% - well below the new regulatory limits. To ensure lab quality results and compliance with methods approved for marine fuel testing (covered under ISO 8217), Petra MAX is fully compliant with ISO 8754, ASTM D4294 and IP 336. In addition to rapid sulfur analysis, Petra MAX delivers simultaneous testing of critical elements like calcium and iron.
